Dick & Barb Cain suggested the same idea I had. Also check the exterior wall behind the cabinet location and see if cold air is entering somewhere. Window and door openings are the most obvious source but missing mortar or bricks which have moved away from trim are also potential culprits. If there is a crawlspace, cold air could be entering from below as well.

thanksI was wondering about the foam idea but didn’t know if it was a good idea or not.Never thought about the outside ..

My son-in-law, who is over 6’ tall (my daughter and I are at the 5’ mark) says that he can feel the “air movement” when he opens the cupboards. So it is a big problem I think. But, they are just starting out so no funds for major renovations.
